12.5.2
When performing a TCNT register read, processing for synchronization with the timer count
operation is performed. If a timer count operation and register read processing are performed
simultaneously, the TCNT counter value prior to the count-down operation is read by means of the
synchronization processing.
12.5.3
When the on-chip RTC output clock is selected as the count clock, the RTC frequency divider
should be reset.
12.5.4
Ensure that the external clock frequency for any channel does not exceed Pck/8.
